This study included 21 patients with patellar symptoms, all of whom had TKA with PS design, who had arthroscopic treatment. 3 Table 1 summarizes the main articles published on the arthroscopic treatment of PCS. Open surgical excision of this nodule is successful in relieving symptoms, but carries a risk of infection and wound complications, which would delay post-operative mobilization. As the knee is moved from flexion to full extension, it is believed that this nodule jumps abruptly from the intercondylar notch in PS knee designs, resulting in the clicking sound ( Fig. Patients present with pain and audible sound when extending the knee from 30° to 45° of flexion. The symptoms are secondary to the formation of a fibrous nodule in the upper pole of the patella that collides with the femoral shield when extending the knee. There are several publications on PCS rates with various designs. PCS typically occurs within the first year after prosthetic surgery. Patellar clunk syndrome (PCS) has traditionally been associated with posterior-stabilised (PS) implants. With regard to intra-articular pathologies that cause pain the first year after a TKA, the most common are infection, instability, poor position of the prosthetic components and soft-tissue impingement. In this article, we review the complications of TKA that can be treated effectively by arthroscopy. The percentage of complications published after knee arthroscopy is < 2%. The arthroscopic procedure is safe if the surgeon is experienced in arthroscopic surgery. Although the role of arthroscopy in TKA has been evaluated less exhaustively, it is an accepted procedure as a method of treating TKA complications.Īrthroscopy has the advantage that it is less painful than open surgery and provides a faster recovery and greater patient satisfaction. It is particularly useful in a wide range of pathologies, such as meniscus, cruciate ligament and cartilage lesions. Knee arthroscopy is one of the most common procedures in orthopaedic surgery. In this subgroup of patients, arthroscopy has the potential to diagnose and treat the causes of post-arthroplasty pain. 1 More and more patients with symptomatic TKA will require the evaluation of an orthopaedic surgeon. The prevalence of total knee arthroplasty (TKA) is increasing and considerable growth in TKAs is foreseen in coming decades as society ages the development of advanced surgical techniques and ameliorations in implant designs have contributed to the improvement in satisfaction after TKA however, the incidence of complications is also increasing as the frequency of TKA increases.
